Yes the answer is recoiled of the Gaian and the hash of attorney then the distance must be bábale of the original number
After 5 seconds the stone will have fallen 49 m
Answer:
Because they want attention
Solution :
Given :
M = 0.35 kg
Total mechanical energy = constant
or
But and
Therefore, potential energy at the top = kinetic energy at the bottom
(h = 35 cm = 0.35 m)
= 2.62 m/s
It is the velocity of M just before collision of 'm' at the bottom.
We know that in elastic collision velocity after collision is given by :
here,
∴
= 0.33 m/s
Therefore, velocity after the collision of mass M = 0.33 m/s
Answer:
Exercise 1;
The centripetal acceleration is approximately 94.52 m/s²
Explanation:
1) The given parameters are;
The diameter of the circle = 8 cm = 0.08 m
The radius of the circle = Diameter/2 = 0.08/2 = 0.04 m
The speed of motion = 7 km/h = 1.944444 m/s
The centripetal acceleration = v²/r = 1.944444²/0.04 ≈ 94.52 m/s²
The centripetal acceleration ≈ 94.52 m/s²
